Spex Seating is intended for users (disabled and/or discomforted) that require specic postural and posi-
tioning support to provide comfort for body function in a sitting posture on wheelchairs for daily activities

al body-posture conditions and/or to help prevent/reduce physical problems associated with sedentary
work or activities.

to tip, potentially causing injury. Always judge the need for anti-tippers or amputee axle adapter
brackets to be added to the Wheelchair to increase stability.

RISK OF ACCIDENT, INJURY, PAIN OR DEATH IF WARNINGS ARE NOT HEEDED
Seek assistance if you are uncertain about any of the following points
1. Installing a Cushion on a wheelchair may disturb the wheelchair’s centre of gravity and cause
the wheelchair to tip backwards potentially resulting in injury or death. Check if anti-tippers or
other adaptations need to be added to the wheelchair to help increase stability.
2. Installation and adjustment of your Dualtec Cushion must only be performed by
a) An authorized Spex distributor or technician
b) A qualied healthcare professional who has undergone appropriate biomechanical training
3. The Dualtec Cushion must have a solid base to install to. A solid seat base pan will provide more
stability to the user (the Cushion won’t sag).
4. This Cushion must be trialled rst to determine its eectiveness in meeting the needs of the user.
The clinician must inspect the user’s skin to ensure that red pressure spots are not developing.
5. The user and/or caregivers should regularly check for skin redness or tissue breakdown. If
redness develops, discontinue the use of the Cushion immediately and consult your doctor or
therapist. The Cushion can be recongured for better positioning.
6. With proper set-up and continued maintenance, the Dualtec Cushion is an excellent candidate
for people who are at risk of skin ulcers, however no Cushion can completely eliminate sitting
pressure or prevent pressure ulcers.
7. Keep the Cushion dry. Moisture is a contributing factor in causing pressure ulcers.
8. We recommend the user to have a good diet and have regular pressure relieving exercises/
therapy to help prevent pressure ulcers.
9. Do not leave the Dualtec Cushion outside overnight or at temperatures below 5° C/41° F. The
Dualtec Cushion should be room temperature before sitting on it.
10. Avoid sharp objects or exposure to excessive heat or open ame.
11. The Dualtec Cushion has been specically designed as a Cushion for users in mobility wheelchairs.
Do not use the Cushion in any way not described and never modify the Cushion.
12. Care should be exercised near open ame or burning cigarettes. Using the Cushion without its
cover increases the risk of ammability and skin damage.
13. Never use the Cushion without the incontinence cover. Failure to do so will reduce the life of
the Cushion.
WARNING
Once the user has nished using the Spex Cushion, it must be refurbished and thoroughly cleaned if it
is issued to another user. Below are the strict guidelines for refurbishing the Spex Cushion. Spex takes no
responsibility for contamination, cross infection, or damage. Spex recommends using AHP (Accelerated
Hydrogen Peroxide) disinfectant wipes. The disinfection product must be used as per the manufacturer
instructions. Spex takes no responsibility for the eectiveness of the disinfecting process.

DUALTEC CUSHION USER MANUAL 6WWW.SPEXSEATING.COM
The Spex Seating System has been successfully crash tested and complies with RESNA WC-4:2012, Section
20 (WC20). The Spex Seating System meets the requirements of ISO 16840-4:2009 and is suitable for use
as a motor vehicle seat when used with an appropriate wheelchair base. Please follow all installation, use
and maintenance instructions within this manual as well as the following transit instructions. If feasible,
the wheelchair user should transfer to the vehicle seat and use the vehicle-installed occupant restraint
systems.
Spex Seating System has been designed to accommodate the proper use of vehicle-anchored belt restraints.
Spex achieved a rating of Excellent (16 out of 16), for ease of properly positioning a belt restraint, and the
degree to which proper belt restraint can be achieved, based on the methods of Annex D. The following
items of the Spex Seating System have been tested and are suitable for use in a motor vehicle:
• Full Height Back Support Models
• Seat Base
• Cushion Models
• Arm and Thigh Supports
• Trunk Lateral Supports
• Head Supports
Note: Back supports that are lower than the user’s shoulder height are not certied and not recommended
for transport in a vehicle. Eg. Vigour Lo and Vigour Mid back supports.
Assembly, Use, Maintenance & Limitations
• Adjustments to the set-up of the wheelchair must only be carried out by a qualied therapist,
professional, or seating technician. Custom contoured/bespoke systems may require a qualied
professional to congure and install the seating system.
• After carrying out any adjustments ensure all bolts, screws and nuts are securely fastened again to
ensure safety when travelling in a vehicle.
• Ensure the top and bottom mounts of the backrest and the front and rear mounts of the seat pan
are installed as far apart from each other as possible to give a stronger 4-point attachment to the
wheelchair frame. Ensure the quick release latches are engaged.
• Do not use the Spex Seating System as a vehicle seat if seating components which have not been
successfully crash tested are used anywhere on the seating system. Spex seating is designed and
certied using only Spex components. Spex is not liable in the event where other manufactured
seating systems are used in conjunction with Spex seating.
• At regular intervals check that all the fastenings on the Spex Seating System have not become loose
during day to day use and re-tighten if necessary.
• Ensure the swing-away laterals are in their locked position before using the seat as a vehicle seat in a
motor vehicle.

DUALTEC CUSHION USER MANUAL 7WWW.SPEXSEATING.COM
Correct Positioning of Belt Restraints
When using the Spex Seating System as a vehicle seat, both a pelvic-
belt restraint and shoulder-belt restraint must always be used. To
correctly position the belt restraints on the wheelchair occupant, the
following must be ensured:
• The pelvic-belt restraint should be worn low across the front of
the pelvis near the junctions of the pelvis and thighs.
• The angle of the pelvic-belt restraint should be between 30° to
75° relative to the horizontal and, ideally, between 45° to 75° to
the horizontal (as shown in Figure 2).
• The belt-restraint buckle of three-point belt restraints should
be placed in contact with the occupant’s body and away from
wheelchair components.
• The junction of the shoulder-belt and pelvic-belt of three-point-
belt restraints should be located near the hip opposite the
shoulder over which the diagonal belt crosses and not near the
midline of the occupant.
• Belt restraints should not be routed outside of the wheelchair
wheels or over the wheelchair armrests, and should not be held
away from the body by wheelchair components or parts.
• Upper torso belt restraints should t directly over, and in contact
with, the middle of the shoulder.
• Belt restraints should be adjusted to t as snugly as possible,
consistent with user comfort.
• Belt restraints should not be worn twisted in a manner that reduces
the area of contact of the belt webbing with the occupant.

The Spex Seating System must only be used for forward-facing
seating in motor vehicles.
In order to reduce the potential of injury to vehicle occupants,
wheelchair-mounted rigid trays not specically intended for use
during travel in motor vehicles must be:
a. Removed and secured separately in the vehicle or
b. Secured to the wheelchair so they will not break free in a crash
and
• Be positioned with a gap of at least 3” (75 mm) between
the back edge of the tray and the wheelchair occupant’s
abdomen and/or chest so as not to interfere with the proper
belt-restraint use, and
• Have energy absorbing padding placed between the back
edge of the tray and the wheelchair occupant.
Alterations or substitutions must not be made to the seating
system structure, parts or components, without rst consulting
Spex.
The use of a postural pelvic belt attached to the wheelchair
base or seat frame is encouraged during travel, but these belts
should be positioned so that they don’t interfere with the proper
positioning of crashworthy belt restraints, and they should not be
relied on for occupant protection in crash situations unless the
postural belt has been designed to comply with, and perform to
the requirements of WC19.
Postural support devices that are not labelled as conforming to
ISO 16840-4 may be used when in a vehicle, but should not be
relied on for occupant restraint.
